CHARLESTON, W.Va. (AP) -- Former Massey Energy CEO Don Blankenship is finishing up a one-year federal prison sentence related to the deadliest U.S. mine explosion in four decades.
According to the U.S. Bureau of Prisons website, Blankenship is set to be released Wednesday from a halfway house in Phoenix, Arizona. He must serve one year of supervised release.
Blankenship was sentenced last year for a misdemeanor conviction of conspiring to violate federal mine safety standards at Massey's Upper Big Branch Mine in southern West Virginia, where 29 workers died in a 2010 explosion.
In January, a three-judge appeals panel affirmed Blankenship's 2015 conviction.
Blankenship, who's 67, served most of his sentence at Correctional Institute Taft near Bakersfield, California.
